摘要：The main objective of this study is the removal of pathogenic bacteria using electrochemical process. The bactericidal effects of electrochemical system containing steel mesh electrode were evaluated from contaminated water with Escherichia coliPseudomonas aeroginosa, Staphylococcus aureous and Streptococcus fecalis at various concentrations. Effect of current density, supporting electrolyte and pathogenic bacterial concentration were studied and kinetic rate of disinfection were determined. The results obtained show that the effect of current density on disinfection efficiency was highest and the concentration of bacteria in the contaminated water and supporting electrolyte concentrations in the electrolyte were more effective. Contaminated water including 100 and 1000 bacteria/ml of E. coli, P. aeruginosa, S. aureus and S. faecalis, were completely disinfected using 0.088 mA/cm2 current in a duration of 5 to 60 min. The rate of the reaction of disinfection is directly related to current density. It is expected that experimental results could be used as a reference for the elimination of pathogenic bacteria using electrochemical process.
